Y= x + 3
1. Find the gradient(slope)
1 - 7 / - 2 - 4
=1
2. Find the y. Intercept ( c )
Y = x + c
Replace by any of the two coordinates given (4 , 7 )
7 = 4 + c
C= 3
Equation => Y = x + 3
Answer:
Step-by-step explanation:
right angle: an angle of 90°
vertical angles: each of the pairs of opposite angles made by two intersecting lines.
complementary angles: either of two angles whose sum is 90°.
Answer: 16
Step-by-step explanation:
let a = your present age
a = 2(a+4) - 2(a-4)
a = 2a + 8 - 2a + 8
a = 2a - 2a + 8 + 8
a = 16 yrs is your age
I did this on a calcalator 3÷5=0.6
3(1,000,000)=3,000,000
3(100,000)=300,000
2(100)=200
3,300,200
